The main object of'this invention is to provide an exceedinglysimple and eificient form of closure for flexible tube containers,

The second object which will be commercially practical on account of its slmple construction and ease of manufacture and assembly.

The third object is tooth paste tubes and the cap or closure cannot become lost; or separated from the container itself;

The fourth object is to reduce the amount of time required foropening' and closingthe container. T hese, and other away in section.

Referringin detail to the drawings, there is shown the usual form ofcylindrical paste container 10 whose discharge end 11 is some what bulging and has projecting therefrom a tapering outlet 12 provided on tooth paste tubes, except that in this case the outlet is not necessarily threaded. On oneside of the endll is formed an eye 13 and on the opposite side thereof is. formed. a. hook141 preferably cast integral e metal of the end 11 and the outletwith th The container itself'consistsof; a .(rap'15- objects, will become more apparent from the specification following as illustrated in the accompanying drawings,-in f which: f'

is to produce a closure to produce a closure'for similar devices 1n wh ch out departing from the tion.

On the'top of the cap 15 is formed an eye 18 through which passes a 'spr'ingwirecapholding clamp 19 whose end 20 isin the formof an eye which hinges on the eye 13', and whose end 21 is also in the formof a closed eye preferably larger than the end 20 to per-j mit same to be used as a handle; and also to. facilitate its engagement with the booklet- 111 the modification shown in Figure5 the clamp 19 isprovidedat its mid portion with. a loop22lwhich passes through the eye 1'8, its function being to definitely locatethe cap 1'5 at the center ofthe clamp 19, Obviously, any other means for accomplishing thisv cap locating object could be femployedwith spirit of this inven- The operation-of the device is. as followsz,

order to open the container-it is merely necessary'to move the end '21 to one side in a manner to disengage the hook 14: and swing the entire clamp and .closure to the position I shown in Figure 4;, or still'further. if desired, giving free access to the paste in the container. To close same a simple reverse operation is all that is necessary, namely bringing the end 21 back into engagement with the hook 14.

The shape of the clamp 19 is such as to require a tension to beplaced thereon when in a closed position, therebyholding the "cap" 15 under a spring tension. f

It is a well knownfact that a great number of devices have beenc'onstructed for this purpose; these having failed to find their way into themarket due to their complicated nature or manufacture or operatiombut mostly on account of their'first cost. With a tooth paste tube particularly is desirable to pre-i vent the closure from becoming lost or; sepj; arate'dl from the container when using same, I and it is equally'desirable when not in use f f thatthe closure will beproperly placed'in. position. It isfor. this purpose thatwehave provided the simplejmechanism illustrated in the drawingsfwhich will require out-a 10 r l. l Q Yr 1,833,231
